BOLT FOR PRISON-DOORS.

SPECIFICATION forming part of Letters Patent No. 353,059, dated November 23, 1886.

Application filed July 7, 1886. Serial No. 207,361.

To all whom it may concern:

Be-it known that I, FRANCIS O. HANSON,

a citizen of the United States, and a resident of Kenton, in the county of Hardin and State of Ohio, have invented a new and useful Bolt for prison -cells or other purposes whereby the control of the whole system is placed in reach of the jailor in the coridor or at any other, convenient point.

The figure in the drawing shows my device in perspective detached from any building.

A represents my lock-box, or that part placed in the corridor or office to be operated therefrom by a key; B, a pinion in the lock; 0, key-hole in the pinion; E, rack operated by the pinion; F, connecting-rod carrying rack E; H L, elbow-lever pivoted at I to bracket K, and atG N to rods F N; O, rack on the rod M; P, pinion on rod Q; B, eccentric on rod Q;

S, bracket in which'rod Q is journaled; T,-

sliding bolt; U, slot in bolt Tin which eccentric R turns; V W X, staples in which bolt T plays.

The object of my invention is to furnish means of looking or unlocking the door of any separate cell in an inside corridorof ajail or any part of the jail from a lock-box placed in an outside corridor orin theoffice or lobby, placing the complete control of the whole system of cell-locks of the jail in thehands of the jailor without causing him to enter the inside of the jailproper to lock or unlock them.

My plan is so simple as to need but little explanation, and will be readily seen on inspection of the drawing.

A series of lock-boxes, A, equal to the number of cellsin the jail, is placed in the lobby, ofiice, or in such other part of the building as desired, but outside of the jail proper. In

(No model.)

each lock-box is a pinion, B, the keyhole of which may beadapted to any key desired. The teeth of this pinion engage with the rack 5 E on the rod F. Said rod extends up any do sired distance, and is pivoted to an L-shaped arm, H L, which is pivoted to a bracket, K, at point I. A rod, M, is pivoted to the other end of the L-shaped arm at N, and this rod 5:: carries rack Oon its outerend, which engages with pinion P on shaft Q. On said shaft, at

' any point desired. is the eccentric R, fitting in a slot, U,-in the sliding bolt T, which slides in the staples V on the bracket S, and also in the staples W X on the door.

, It will be readily seen that when the key is placed in the key-hole G and turned the pinion B is revolved, the rack E is operated, and the rod F is moved up or down as thekey is turned to the left or right, and the rod M is operated through the pivoted L-shaped arms H L. As the rod M is moved the rack 0 turns the pinion P, revolvingthe shaft Q, and causng the eccentric R to throw the bolt T back or forth into or out of thestaples WV X, as desired. Any number of cells can be thus operated, the lock-boxes all being placed in the office or lobby, and rods run to each cell similar to those shown and described above, all those of one corridor being neatly inclosed in a case, so as to be concealed from view.

Whatv I claim is- The combination, with the pinion B, provided with a key-hole, O,of lever F, having rack E thereon, the pivoted elbow-lever H L, rod M, provided with rack O, pinion P, shaft Q, having eccentric R thereon, and bolt '1, adapted to be operated by said eccentric, substantially as shown and described.
